| 4–8 | Hull serial number | 45678 | INTNL MRN COMBUSTN INC's own production number for the specific hull (the letters I, O, Q are never used). |

| 10 | Certification year | 4 | Last digit of the certification year. |

INTNL MRN COMBUSTN INC HIN FAQ
What does a INTNL MRN COMBUSTN INC HIN look like?
It starts with the three characters "MXV" — the Manufacturer Identification Code the US Coast Guard assigned to INTNL MRN COMBUSTN INC — followed by a 5-character hull serial and a 4-character date code, 12 characters total. INTNL MRN COMBUSTN INC built hulls across both HIN eras (1980–1990): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three.
Is INTNL MRN COMBUSTN INC still in business?
USCG records list INTNL MRN COMBUSTN INC as out of business since 1990. That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
How do I decode the year on a INTNL MRN COMBUSTN INC HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. INTNL MRN COMBUSTN INC built hulls across both HIN eras (1980–1990): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
Where is the HIN on a INTNL MRN COMBUSTN INC boat?
On the outside upper-starboard (right) corner of the transom, within two inches of the top — required by 33 CFR 181.29. Since August 1984 an identical duplicate HIN is also molded into an unexposed interior location as an anti-theft measure. Both should match the title, registration, and insurance card exactly.
Is the "MXV" MIC the same as a INTNL MRN COMBUSTN INC serial number?
No. "MXV" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies INTNL MRN COMBUSTN INC. The hull serial number is characters 4–8: INTNL MRN COMBUSTN INC's own production number for that specific boat (the letters I, O, and Q are never used). The full 12-character HIN combines the MIC, the serial, and the date code.
Can a INTNL MRN COMBUSTN INC HIN tell me the exact model?
Not on its own. A HIN encodes the builder, hull serial, certification month/year, and model year — not the model name or length. Match the decoded year and serial against INTNL MRN COMBUSTN INC records, the title, or a marine survey to confirm the exact model and configuration.
